Orabubble Co., Ltd. (Headquarters: Kanda-machi, Miyako-gun, Fukuoka Prefecture; Representative Director: Satoru Ogawara) announces that its mouthpiece-type oral irrigator "Orabubble", which utilizes fine bubble technology, has been featured as a healthcare venture and related technology in the market research report "2026 Current Status and Outlook of Healthcare Ventures" published by Yano Research Institute Ltd.
■ Market Background
With the progression of an aging society, maintaining oral hygiene is considered one of the important elements of daily care. On the other hand, in nursing care settings, balancing safety and efficiency is required due to labor shortages and increasing workloads. According to our calculations, the domestic oral care-related market is worth about 400 billion yen annually, and is expected to expand further with the aging population. Against this background, Orabubble was developed as a mouthpiece-type oral irrigator utilizing fine bubble technology, and is proposed as a new approach to conventional oral care methods.
■ Development Background
This product was developed after the company representative, who is both a physician and the manager of a metal processing company, experienced nursing care for his own father. While realizing the relationship between oral hygiene and systemic health in nursing care settings, he experienced firsthand that the oral environment, such as periodontal disease bacteria, often leads to aspiration pneumonia. On the other hand, there are many situations where sufficient oral care is difficult due to labor shortages and safety issues in the field. To address these issues, by leveraging medical knowledge and manufacturing technology, and encountering fine bubble technology, he developed the mouthpiece-type oral irrigator "Orabubble".
■ Features of "Orabubble"
1. Can be cleaned with "only water" without electricity due to fine bubble technology
Using a Venturi structure, Orabubble generates invisibly extremely small bubbles of less than 1/1000 mm (less than 1 μm in diameter) using only regular tap water flow, and this water flow full of ultra-fine bubbles washes the oral cavity. Ultra-fine bubbles enter every crevice of the entire mouth, including between teeth, periodontal pockets, and even the tongue and oral mucosa, absorbing and washing away dirt with "high cleaning characteristics." It is a completely new oral irrigator that "washes the entire inside of the mouth."
2. Reducing nursing care burden and improving work efficiency
By holding the mouthpiece in the mouth, the fine bubble water flow circulates throughout the entire oral cavity, which can be utilized as an option for performing oral care. This helps to avoid the risk of caregivers being bitten when putting their fingers directly into the oral cavity, and reduces mental and physical burdens. In addition, the entire oral cavity can be cleaned in a short time, improving work efficiency in nursing care settings.
3. Structure designed to easily drain water from the oral cavity
This product adopts a structure equipped with a discharge route for cleaning water, and is designed to consider the retention of water in the mouth during use. (*However, this is not applicable to those who experience aspiration with every meal.)
Unique water supply and drainage system
This product is registered in the Technical Aids Information System (TAIS) as a device for such oral care purposes.

■ Response at Exhibitions
This product was exhibited at the following specialized exhibitions and garnered interest from medical and nursing care professionals.
Medical Japan 2025
Kochi Welfare Equipment Exhibition 2025
Techno-Aids Association Symposium Concurrent Exhibition
At the exhibitions, there were inquiries regarding the product structure and introduction from nursing care facility personnel, medical institution personnel, and welfare equipment-related businesses.
■ Sales System and Future Development
With J-Alliance Co., Ltd. (Headquarters: Osaka City, Osaka Prefecture) as the general agent, we are proceeding with the construction of a sales system for nursing care facilities, medical institutions, and related businesses nationwide. Currently, we are receiving inquiries regarding handling from businesses in the medical and nursing care fields, and we will aim to further expand introduction opportunities in the future. In addition to product sales, we are also considering support for obtaining the "Oral Function Improvement Addition" at nursing care facilities. By combining this with a system that easily records and creates forms on smartphones, we will promote introduction while considering the burden on the field, and contribute to the operational support of nursing care facilities.
